The 100:1 ratio means the output shaft turns once for every 100 input revolutions — typical for indexing tables, conveyor drives, or positioning axes where high torque multiplication is needed at low output speed. Continuous output torque is 120 N.m at 100 rpm and 30 °C; maximum intermittent torque reaches 192 N.m under the same conditions. The 94 % efficiency means about 6 % of input power is lost as heat through the gear mesh — a factor when sizing the upstream motor and checking thermal rise in a sealed enclosure. Torsional backlash is 16 arcmin — that is the angular play between input and output when reversing direction. For positioning applications, this sets the repeatability floor: a load reversing through the gear train will see up to 16 arcmin of lost motion before the output responds. If the application needs tighter positioning, a lower-backlash gearbox (e.g. 3–5 arcmin) would be required. ## Sourcing an obsolete planetary gearbox — lifecycle reality and supply posture Schneider Electric lists the GBX0801000703F as obsolete. No official successor or cross-reference part number is recorded. This means the original manufacturer no longer produces it, and the only supply channel is independent surplus or broker inventory. The gearbox carries a 30000-hour service life at 100 rpm and 30 °C, lubricated for life — no field regreasing interval. When sourcing a replacement for a line-down situation, confirm the remaining service life of the unit being replaced against the new-old-stock unit's production date; shelf-aged lubricant may reduce effective life. Available through independent distribution against an RFQ. Quantities are lot-specific — no blanket stock commitment. The IP54 shaft output rating means the gearbox is protected against dust ingress and splashing water at the shaft seal, but not washdown or submersion; if the original installation was in a wet environment, verify the seal condition on any surplus unit before commissioning. ## Mechanical interface and load limits for field fit Output shaft is C45 steel. Maximum radial force (Fr) at mid-span on the output shaft is 650 N for 30000-hour life, 950 N for 10000-hour life — both at 100 rpm and 30 °C. Maximum axial force (Fa) is 1200 N for 10000-hour life, dropping to 900 N for 30000-hour life. These limits govern belt-pulley or chain-sprocket loads directly on the output shaft; exceeding them shortens bearing life faster than the gear mesh wears. The torsional rigidity is 6.3 N.m/arcmin — a measure of how much the gear train winds up under load. For a servo-driven axis, this stiffness combines with the motor's torsional resonance to set the gain ceiling in the servo loop. Noise level is 60 dB at 1 m, no-load — roughly the sound of a quiet office. Under load, expect a few dB higher from gear mesh harmonics. The straight-tooth design is inherently noisier than helical; if the application is in a noise-sensitive area (e.g. near operator stations), a helical planetary would be quieter.","metaTitle":"Schneider Electric GBX0801000703F Planetary Gearbox, 100:1","metaDescription":"Schneider Electric GBX0801000703F planetary gearbox, 80 mm diameter, 100:1 reduction, 120 N.m continuous torque, 94% efficiency.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Gear Reducers & Gearboxes"],"specifications":{"Efficiency":"94 %","Noise level":"60 dB 1 m, no-load","Gear box type":"Straight teeth","Housing Colour":"Black","Shaft material":"C 45","Reduction ratio":"100:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Compatibility code":"GBX","Torsional rigidity":"6.3 N.m/arcmin","Maximum output torque":"1699.3 lbf.in (192 N.m) 100 rpm 86 °F (30 °C)","Nbr. of units in pkg.":"1","Service life in hours":"30000 h 100 rpm 86 °F (30 °C)","Additional information":"Lubricated for life","Maximum axial force Fa":"1200 N 100 rpm, during 10000 hour at 30°C 900 N 100 rpm, during 30000 hour at 30°C","IP Degree of Protection":"Shaft output IP54","Maximum radial force Fr":"650 N 100 rpm, force applied at mid-distance from output shaft during 30000 hour at 30 °C 950 N 100 rpm, force applied at mid-distance from output shaft during 10000 hour at 30 °C","Continuous output torque":"1062.09 lbf.in (120 N.m) 100 rpm 86 °F (30 °C)","Gearbox external diameter":"3.1 in (80 mm)","Product or Component Type":"Planetary gearbox","Maximum torsional backlash":"16 arc.min","Ambient Temperature For Operation":"-13...194 °F (-25...90 °C)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/20102a2eb610d54d6ecf96696230f020.pdf","sourceUrl":"https://www.se.com/ca/en/product/GBX0801000703F/gearbox-with-straight-teeth-gbx-ø-80-mm-reduction-1001-16arcmin-120-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX0801000703F/alternatives.json"},"ai":{"faq":[{"question":"What is GBX0801000703F's listed efficiency?","answer":"The listed efficiency is 94 %.
